Maximum Stepover and Tool Engagement mutually calculate. Set one to dynamically calculate the other. For example, if you have a 1-inch endmill and set the Maximum Stepover to 0.5, the Tool Engagement calculates to 90 degrees. If you set the Tool Engagement to 90, the Maximum Stepover calculates to 0.5
This is the key setting for TrueMill. Clearly understand this setting to effectively use TrueMill.
SURFCAM creates the tool path so that the actual engagement of the tool is never greater than the value you use.
Examples, Tool Engagement
If you set Tool Engagement to 90, the engagement angle never exceeds the following.
If you set Tool Engagement to 135, the engagement angle never exceeds the following.
Maximum Stepover and Tool Engagement also appear under the Finish Floor heading, where they apply only to the Finish Floor cutting passes.
